Quiche is a French dish, but one version says that it was invented by German chefs. The fact is that they did not want to throw away the remains of the dough that was made for bread. These leftovers were not enough to make a full pie, but there was enough for the base. The filling was a mixture of milk and eggs with various additives. Later, this simple dish was appreciated in France, but they made their own adjustments. The dough, for example, became sandy.
